    Sceptre X24WG-1080P Problems

    Well Howdy from Montana!
    As a result of finding this fantastic resource, several purchases have been made of broken gear. Because I am a cheap bas...;.

    I have read many success stories on this board and that's what hooked me.

    With the introductions out of the way, here is my problem:
    When the power button is pushed the led comes on and rig seems like it's warming up but no picture then the led just starts flashing.

    Upon opening the case I removed the psu and can visually see no problems. So that's where you board angels come in. Can someone point me in the direction I should go to fix this rig?

    Thanks in advance!

    1) Hookup a working computer with your favourite wallpaper as the desktop to the lcd. Can you see the image if you shine a flashlight on it?

    2) Do you have a multimeter? If yes, what are the DC voltages on connector CN801 (all 11 pins).

        I suspect that part of the board is darkened from heat but the light is too dim for it to be seen in the pictures. Any capacitors in a darkened area are likely bad.

        I don't like those purple Hermei with the fake Panasonic T-vent either and that's where I'm expecting the discoloration.

          Ok, I was going to check the pin voltages as stated but I don't know which ground to use. I'm guessing the one in the connector.

          It's been raining here so I have not got a good clear closeup of the underside of the psu, yet. I will asap.

          One more question can I check these voltages out of the unit or must I hook it all back into the monitor? The way this unit is designed is the psu mounts to the rear cover and has cables that go to the lcd. So checking it all connected I will have to set the live psu on the back of the lcd with cardboard or something to insulate it.

          Thanks again for all help!

            Use a ground screw for ground.

            We prefer if everything is hooked up. Use cardboard or something to insulate the boards so they don't short out.

              Just communicating with you folks fixed my monitor!!!

              I reassembled the unit today as per retiredcaps and hooked it up to a computer and much to my good fortune it is up and running. Great picture, no glitches!

              WOW!

              So I want to thank you very much for your help!!!

              Now my LG 42" plasma TV went out a week ago. I have since pulled it apart and I see several bloated caps. Parts are on the way and I'll be installing them soon. If anyone is interested I'll start a thread.

              Thanks again!

                Yes, start a new thread even if you fix it. I'm always interested in what boards look like inside.

                  Well the only thing and I mean only thing I found was the connector that went from the switch board to the psu was not seated properly. As for any other visual problems, there weren't any. So that's all I know.

                  I'm not an electronics tech by any means, but this stuff is already broken and I'm willing to go inside and learn!

                  Thanks again!!!
